City Size
Located in south of northeast China, Shenyang is the center of Northeast Asia Economic Circle and Circum-Bohai Sea
Economic Circle and the multifunctional hub city connecting Yangtze River Delta, Pearl River Delta and Beijing-Tianjin-Hebei
Region to Kanto Region. With 10 districts, 2 counties and 1 county-level city under its jurisdiction, the city has a total area ofover 12,984 square kilometers and an urban area of 3,495 square kilometers. With a permanent population of 8,291,000
people and a registered population of 7,304,000 people in 2015, the city realized a total output value of 728.05 billion yuan.

Climatic Conditions
Having a temperate semi-humid continental climate,
Shenyang has an annual average temperature of 6.2
to 9.7 ℃ . From the complete record since 1951,
Shenyang has the extreme highest temperature of
38.3 ℃ and the extreme lowest temperature of 32.9 ℃ in central urban area, with a temperature
difference exceeding 70℃. Shenyang has a yearly
precipitation of 600 to 800 mm, with a yearly average
precipitation of 716.2 mm in urban area in the periodof 1951 to 2010, and has a yearly frost-free period of
155 to 180 days. Due to the monsoon, theprecipitation occurs mainly in summer, with big
temperature difference and four distinctive seasons.
The winter period lasts for a long time, nearly 6months.

The dust pollution mainly comes
fromblowing

and dust of local roads. Totally 7
sand and dust weathers occurredin 2016.

andOrganic exhaust gas mainly
consists of restaurant oily fumeand disorganized VOC fromindustries of rubber, printing,chemical medicine, etc.

Coal Usage
Shenyang had a total coal consumption of 24.2717 million tons in 2016, including a coal consumption of 21.3153 million
tons from industrial pollution sources that makes 87.82% of the total coal consumption of Shenyang City.

Thermal Power
Generation
Till now, Shenyang totally has 9 thermal
power stations, which has a grossgeneration of 12 billion KWH. In 2016,Shenyang upgraded and reconstructed
all power stations for pollution
abatement, and the main pollutants aredischarged as per: TSP: 20mg/m³;
Sulfur dioxide: 50mg/m³; NOx:100mg/m³.

Industrial
Production
As mentioned above, due to the special climatic conditions Shenyang has adjusted thein Shenyang, the yearly heating period is 6 months to meet industrial structure vigorously.
the heating demand of 8 million people for half a year, more Currently, Shenyang has
than 7 million tons of coals need to be burned, and thus,
equipment manufacturing
just the heating occupies nearly one fourth of the standard industry as the main industry,coal burning amount of Shenyang. Currently, Shenyang has and has only 1 large-scale
performed National Comprehensive Emission Standards for chemical enterprise and has
Atmospheric Pollutants: TSP: 30mg/m³; Sulfur dioxide:
no heavy pollution industries ofplate glass, cement, steel, etc.
200mg/m³; NOx: 200mg/m³.

Reduce Coal Use
Compared with 2015,
Shenyang reduced coal use by
1 million tons in 2016,
increased use of natural gas by1623%, and increased thesolar power generation of
500000 KWH.

In 2016, the quality of coalburned in Shenyang improved
largely, including that coal ash

Pollutions of Motor Vehicle Exhaust

Public Welfare
Publicity

Government
Subsidy

As organic exhaust gases discharged frommotor vehicles cause many diseases andthey are discharged at the height basicallyequal to breathing height, widely publicize theconsequences of exhaust gas discharge, set
up green-label roads, and forbid the pass ofyellow-label vehicles on the green-label roads.

Since 2016, Shenyang Municipal Government has
released a subsidy of 0.228 billion yuan for yellowlabel vehicles. A joint-review hall is set up by Traffic
Department, Environmental Department, Public
Security Department, Financial Department andService Industry, the public can complete allprocedures within 1 day and get subsidy while
scrapping.

Scrap

Shenyang has scrapped totally 56,645 yellow-label
and old vehicles, and has upgraded 361 petrol
stations, 7 oil storage tanks and recycled oil gasesof 261 oil tank trucks.

Dust Control
Industrial dust is mainly
controlled by controllingenterprise production materials
and industrial waste. Shenyang
forbids open-air storage of coal,sandstone and construction
residual soil, and controls by
wet spray on windy days.
Shenyang reduced industrial
dust by 24% in 2016.

RoadDust
Road dust is mainly
controlled by increasing wet
cleaning percentage of roads.
In 2016, Shenyang realized
wet cleaning for all
secondary and above roads,
100% of wet cleaning.
Shenyang reduced road dust
by 57.1% in 2016.

Industrial
Dust

LivingDust
Living dust is mainly controlled by controllingstorage of living waste at the connection ofurban and rural areas and the scattereddisorder-dirty issues of small-sized production
and processing enterprises. Shenyang
reduced living dust by 8% in 2016, but theliving dust level was still higher than thenational average level. We will prioritize thecontrol of living dust in 2017.

Control on Organic Exhaust Pollution

Special Control toTertiary Industry

Control on Industrial
Organic Exhaust Gas

Shenyang Municipal
Government released financial
subsidy of 10 million yuan in2016 to control oily fumepollution of small catering
industries. Shenyang rectified
totally 340 catering enterprisesthat have oily fume pollution.
The catering enterprises withoily fume discharge in urban
area are all equipped withelectrostatic purification
devices.

Aimed at the industry featuresof Shenyang, Shenyang
focused efforts to rectify theorganic exhaust gas pollutionsof rubber & tire industry,
printing industry, chemical andmedicine industry andautomotive industry in 2016, tostandardize the exhaust gases
discharged by enterprises byRTO, Light Oxygen Catalyzing,
Active Carbon Adsorption, etc.,
and Shenyang prohibiteddisorganized discharge oforganic exhaust gases.

III Achievements of Environmental Control
In 2016, Shenyang had 249 fairly good or good daysin ambient air quality, which increased by 42 days
compared with 2015, and reduced light pollution,
middle-level pollution, heavy pollution and severe
pollution by 3 days, 19 days, 12 days and 7 days
respectively.

Compared with 2015, Shenyang increased by 5 days and 31 days
for O3 and PM10 as primary pollutants respectively, and reducedby 3 days, 11 days and 30 days for NO2, SO2 and PM2.5 asprimary pollutants respectively. Except that CO didn’t exceed
standard and exceeding standard ratio of O3 rose on year-on-yearbasis, the remaining four exceeding standard ratios all reduced tocertain extent on year-on-year basis.
